My son (born 12-30-2005) is still not using his verbal skills. I have been a stay-at-home mom his entirer life. He has a very bad temper, when he does not get his way or what he wants. He loves playing with trucks, cars, etc. He will make the sound "voom-voom". He has is "own lanuage" as my husband and I call it. He just rambles made up words. The only words we understand is, "Mommy, Daddy, BaBa, Milk, Jouce (juice), Baby, Puppy, Bird, Play, This, That, Woof, Meow, Moo-Cow, No, Okay, Trash, Bat-Tem (Bath-Time), GiGi (my mom's nick name), Welo (spanish slang for grandpa-my husband's dad), Toy Story, Buzz, Woody". He can not speak senentces. He has consumed more TV shows (Nick Jr., PBS Sprout) then needed. Also, he watches movies (ToyStory, Cars, Shrek, Ice Age, Wall-E, Bee Movie, etc.) mainly animated cartoons. We can comunicate with him... for example: We ask him to help take something to the trash and he will go straight to the trash with that item. We ask him to kiss his sister (6 mths) and he will give her a kiss. He understands a few commands. Also, we are starting to point and say what we are pointing to and he tries to say the word. He is not potty-trained. We say go to the potty and he says "No!" but, we still take him anyway and he will go pee-pee on the potty. He sometimes screams, rather then talks. My parents and my in-laws think it's his hearing and that we need to get his ears checked. His pediatrician said at his 4 yr. check-up that he would evaluate him and check his ears. I'm very concerned and want him to start developing. If, there is anyway you could advise me on what to do in the mean time, I would greatly appreciate it. Thanks, so much!
